5b4ca80479 wifi: rtw89: ps: update data for firmware and settings for hardware before/after PS
For MLO supported IC, send H2C command to firmware before PS with link
information for each PHY for MLO to work properly. And re-init hardware
settings regarding to RX descriptor information after PS.

8c86036693 wifi: rtw89: ps: refactor channel info to firmware before entering PS
In PS mode, firmware needs hardware parameters related to channel info
to configure hardware itself. Before entering PS, driver prepares these
info to firmware via firmware H2C command.

Since firmware only consider PS for single one vif, change the argument
of entry function to rtwvif, and only consider first link for this old
H2C command that only support legacy.

1015d61570 wifi: rtw89: ps: refactor PS flow to support MLO
Firmware can only support PS on single one VIF operating in station mode,
so argument of PS entry rtw89_enter_lps() should be rtwvif insetad of
rtwvif_link.

To enter PS under MLO, for each rtwvif, driver sends H2C command to tell
firmware which mac_id will enter PS one by one, and afterward asks
firmware to enter deep PS.

In the original flow, the crystal_cap might be calculated as a negative
value and set as an overflow value. Therefore, we added a check to limit
the calculated crystal_cap value. Additionally, we shrank the crystal_cap
adjustment according to specific CFO.

The original handling will iterate all active links under the given sta
and apply the changes to each. Now, stack tweaks ops from sta_rc_update

iteration looks redundant. So, refine it to apply the changes to the link

a6db83bef0 wifi: rtw89: apply MLD pairwise key to dynamically active links
In MLD connection, a pairwise key should work on all active links. And, we
take just one entry in security CAM for one pairwise key. (It means we will
reuse one single entry for all links.) Originally, we already applied the
security CAM entry of pairwise key to deflink's address CAM.

However, links can be activated dynamically. So now for pairwise keys, each
rtw89_sta records the IDs of the security CAM entries. Then, when driver is
notified that some links are active via change_sta_links(), we apply target
pairwise keys to them according to the record.

To support MLO, implement change_vif_links() and change_sta_links() ops.
Basically, we follow arguments to set/clear links. One special thing is
that when vif is idle, i.e. no connection, link id 0 is set up by us for
default uses. So, when bitmap of vif links change from 0x0 to non-zero,
we clear the default one first. And when bitmap of vif links change from
non-zero to 0x0, we set up a default one at the end.

144c6cd24b wifi: rtw89: 8922a: configure AP_LINK_PS if FW supports
After FW v0.35.46.0, for AP mode, RTL8922A FW supports a new FW feature,
called NOTIFY_AP_INFO, to notify driver information related to AP mode.
And, one function of it is to monitor PS states of remote stations. Once
one of them changes, FW will send a C2H event to tell driver. With this
FW feature, we can declare AP_LINK_PS.

For now, driver still needs to determine if a frame is ps-poll or U-APSD
trigger. So, add the corresponding RX handling in driver, which activates
only when at least one AP is running.

ce5dea83ee wifi: rtw88: usb: Enable RX aggregation for 8821au/8812au
USB RX aggregation improves the RX speed on certain ARM systems, like
the NanoPi NEO Core2. With RTL8811AU, before: 30 Mbps, after: 224 Mbps.

The out-of-tree driver uses aggregation size of 7 in USB 3 mode, but
that doesn't work here. rtw88 advertises support for receiving AMSDU
in AMPDU, so the AP sends larger frames, up to ~5100 bytes. With a size
of 7 RTL8812AU frequently tries to aggregate more frames than will fit
in 32768 bytes. Use a size of 6 instead.

net: make RSS+RXNFC semantics more explicit

The original semantics of ntuple filters with FLOW_RSS were not

 test coverage for this functionality.
Also teach ethtool_check_max_channel() about this.

a64499f618 net: ethtool: account for RSS+RXNFC add semantics when checking channel count
In ethtool_check_max_channel(), the new RX count must not only cover the
 max queue indices in RSS indirection tables and RXNFC destinations
 separately, but must also, for RXNFC rules with FLOW_RSS, cover the sum
 of the destination queue and the maximum index in the associated RSS
 context's indirection table, since that is the highest queue that the
 rule can actually deliver traffic to.
It could be argued that the max queue across all custom RSS contexts
 (ethtool_get_max_rss_ctx_channel()) need no longer be considered, since
 any context to which packets can actually be delivered will be targeted
 by some RXNFC rule and its max will thus be allowed for by
 ethtool_get_max_rxnfc_channel().  For simplicity we keep both checks, so
 even RSS contexts unused by any RXNFC rule must fit the channel count.

9e43ad7a1e net: ethtool: only allow set_rxnfc with rss + ring_cookie if driver opts in
Ethtool ntuple filters with FLOW_RSS were originally defined as adding
 the base queue ID (ring_cookie) to the value from the indirection table,
 so that the same table could distribute over more than one set of queues
 when used by different filters.
However, some drivers / hardware ignore the ring_cookie, and simply use
 the indirection table entries as queue IDs directly.  Thus, for drivers
 which have not opted in by setting ethtool_ops.cap_rss_rxnfc_adds to
 declare that they support the original (addition) semantics, reject in
 ethtool_set_rxnfc any filter which combines FLOW_RSS and a nonzero ring.
(For a ring_cookie of zero, both behaviours are equivalent.)
Set the cap bit in sfc, as it is known to support this feature.

4c54e9497d net: sparx5: add missing lan969x Kconfig dependency
The sparx5 switchdev driver can be built either with or without support
for the Lan969x switch. However, it cannot be built-in when the lan969x
driver is a loadable module because of a link-time dependency:

arm-linux-gnueabi-ld: drivers/net/ethernet/microchip/sparx5/sparx5_main.o:(.rodata+0xd44): undefined reference to `lan969x_desc'

Add a Kconfig dependency to reflect this in Kconfig, allowing all
the valid configurations but forcing sparx5 to be a loadable module
as well if lan969x is.

Continue the process of making a dscp_t variable available when setting
.flowi4_tos. This series focuses on the BPF helpers that initialise a
struct flowi4 manually.

The objective is to eventually convert .flowi4_tos to dscp_t, (to get
type annotation and prevent ECN bits from interfering with DSCP).

8aefcfa04b tools/net/ynl: add async notification handling
The notification handling in ynl is currently very simple, using sleep()
to wait a period of time and then handling all the buffered messages in
a single batch.

This patch adds async notification handling so that messages can be
processed as they are received. This makes it possible to use ynl as a
library that supplies notifications in a timely manner.

- Add poll_ntf() to be a generator that yields 1 notification at a
  time and blocks until a notification is available.
- Add a --duration parameter to the CLI, with --sleep as an alias.

./tools/net/ynl/cli.py \
    --spec <SPEC> --subscribe <TOPIC> [ --duration <SECS> ]

The cli will report any notifications for duration seconds and then
exit. If duration is not specified, then it will poll forever, until
interrupted.

Here is an example python snippet that shows how to use ynl as a library
for receiving notifications:

    ynl = YnlFamily(f"{dir}/rt_route.yaml")
    ynl.ntf_subscribe('rtnlgrp-ipv4-route')

    for event in ynl.poll_ntf():
        handle(event)
